I'll answer the questions below, although some are out of date i hope it will aide others in the future. To Superspanky's question(scarey name) No it should not interupt any songs, the 55 bard in our guild has two swords with aug PROCs and niether interupt his songs.
To zasrner's Question. if not a pally or SK, I see you are a warrior, anger two is great and a far better agro keeper. However since updates warriors can keep agro a little better but i'd still go for anger as warrior deal out the best melee DMG anyway.
As to Jarsh question, yes procs can stack on the same weapon, I have seen this happen on many occasion on my own weapons and most of all dual wielders especially rogues who count on a few proc's going of on one hit.
Hope it helps and goodluck.
